I have just managed to get hold of a brand new, never used pair of gold lenses for my titanium juliets, and am now considering what to do with the original gold lenses.. They have quite a few light scratches to the gold iridium which is noticeable when wearing them. I did consider selling them but thought they would fetch very little and then I remembered reading on here about removing the iridium coating using alcohol solution. I also read something about polishing scratched iridium using mild toothpaste or baking soda/water mix although I am sceptical about this working! If I could remove the iridium would this leave me with a light brown lens? Might be a nice alternative to my gold lenses. (my brother works in a lab so could get me some strong alcohol if needed) Anyone tried polishing? Is that nonsense? Just found it on a google search! Thanks in advance for any opinions/advice!!
